LOOM-SHUTTLE.

SPECTPTCATION forming part of Letters Patent No. 319,866, dated June 9; 1885. Application filed February 4, 1 884. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN P. THoMPsoN, a citizen of the United States, and a resident of Phoenix, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Loom-Shuttles; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a top view of one end of a loomshuttle provided with my improvements. Fig. 2 is a perspective front view of the same. 3 is aperspective rear view of the same. Fig. 4 is a sectional view on line :0 00, Fig. 1. Fig. 5 is a side view of the shuttle end, and Fig. 6 is a perspective detail view of the adjustable eyepiece.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to loom-shuttles, and it contemplates certain improvements upon the shuttle for which Letters Patent No.

284,089, were granted to me on the 28th day of August, 1883; anditconsists in the improved construction and combination of parts of a shuttle having an eye-piece, through a portion of which the threador filling passes, and into which the filling may be easily slipped,as hereinafter more fully described and claimed.

, In the accompanying drawings, the letter A indicates the shuttle-body, which has the usual recess, B, in which .the bobbin is placed, and which recess is contracted toward one end to form a throat, O, at which point an angular or V-shaped slot, D, is cut through the front side of the shuttle-body. A screw-threaded perforation, E,passes transversely through the shuttle-body, intersecting the throat, its forward end opening at the end of the V-shaped slot, and a screw-threaded eye-piece, F, having a nick, G, in its rear end for the application of a screw-driver, fits in this perforation. The forward end of this eye-piece is hollow, as shown at H, and is spirally slotted to form a spiral tongue,I. Aspirally-curved wire guide, J, curved in the same direction as the spiral Fig.-

tongue, is secured in the wood of the shuttlebody at the forward end of the screw-threaded perforation E. A wire hook or guide, K, is secured in the throat, having one end sufficiently clear off the side and bottom of the said throat to allow the filling to be slipped into it, which hook serves to confine the filling and guide it to the V-shaped slot. WVhen the shuttle is to be threaded,the end of thefilling is drawn straight out toward the point of the shuttle and placed in the upper portion oftheV-shaped slot,when, by bearing down upon the filling, it will be slipped into the hook K. The end of the filling is thereupon drawn back from the point of the shuttle, drawing it into the lower portion of the V-shaped slot, which will guide it to the spiral wire guide in the end of the threaded perforation, and by now making a-circular motion of the hand holding the filling, following the spiral of the wire guide, as indicated by the arrow in Fig. 5, the filling will enter the hollow end of the eye-piece, passing out through the said hollow end, the spiral tongue at that end confining the filling as the shuttle travels forward and back.

The tension upon the filling may be increased after the eye-piece has been threaded by turning the said eye-piece within its perforation by means of a screw-driver insertedinto the notch at the end of the eye-piece in the direction of the spiral tongue, when the filling will bear against the end of the spiral slot and be partly or entirely wound around the eyepiece, which will cause the filling to meet with less or more frictional resistance.

Having thus described my invention, I claim- 1. The combination, with a shuttle body having a transverse perforation and a slot extending from the bobbin-holding recess to the said perforation, of an eye-piece fitting in the said transverse perforation, having a hollow end slotted to form a spiral tongue, as and for the purpose shown and set forth.

2. The combination, with a shuttle body havingatransverse perforation and a slot extending from the bobbin-holding recess to the said perforation, of a thread-guide at the inner end of the'said slot, and an eye-piece fittingg'u the transverse perforation,having a hollow end slotted to form a spiral tongue, as and for the purpose shown and set forth.

3. The combination, with a loom -shutt le body provided with a V-shaped slot, D, of the adjustable eye-piece formed with a hollow end, and slotted spirally at that end to form a spiral tongue, as and for the purpose shown and set forth.

4. The combination of a loom-shuttle body provided with a V-shaped slot, D, with the spiral wire guide J and the adjustable eyepiece formed with a hollow end, and slotted spirally at the said end to form a spiral tongue turned in the same direction as the spiral guide, as and for the purpose shown and set forth.

5. The combination of a loom-shuttle body JOHN POLK THOMPSON.
